Found: Children's series about different monster families, 2000s

I remember seeing these in the school library in the 2000s - they were Scholastic Book Fair kinda books, and each one was about a different classic monster family (vampire family, werewolf family, mummy family, invisible family ...). They were quite short books, in the vein of Geronimo Stilton, for younger kids, not full-on chapter books.
On the covers were cutesy line-style illustrations of the parents and their kids posing for a portrait, in very simple colour schemes - black white and red, or maybe purple/pink.
I have a feeling the concept was that all these families lived on the same street or something? I've tried searching, but there's so many similar books that came out around then, and none of them are the series I remember.

Thanks in advance!

>1 Mimibix: Could these be the Wacky Families books? It looks as if they were published for (North) American audiences by Stone Arch Books, which used a similar red box logo on their covers as Scholastic did/does.

>2 slimikin: Verrrrrry similar, but not it sorry - I remember the covers were mainly white, and each one had the whole family posed like for a photo. Thanks anyway!

>3 Mimibix: If the covers were mostly white, the Freak Street books probably aren't the right books either (unless Scholastic did a variant cover that I can't find online anywhere), but is the art and portrait style on the covers close to what you remember? If so, that might help searchers track your books down.

>4 slimikin: Ooh yes, Freak Street is the series!! Don't know where I got the white cover idea from haha, but those illustrations are exactly it. Thank you very much!

>5 Mimibix: Oh, even better! I'm so glad that turned out to be the series you were looking for.
